中山市1996—2000年疟疾流行状况与监测

中山市疟疾发病率由1996年的31.9/10万,降到2000年5.0/10万,在“九五”期间发病率下降84.3%,疟疾防治工作从控制流行转入巩固和监测阶段。五年共检查“三热”病人8256例,阳性1277例,平均阳性率为15.5%;其中本地人口病例277例,占总病例数的21.5%。外地人口病例1011例,占总病例数的78.5%。“九五”期间,我市各项基础设施基本完善,流动人口相对稳定,再加上疟防工作的落实,使我市疟疾病例结构由内源转入输入,输入病例占病例总数从9.1%上升为46.4%,这一流行病学特征的改变,对我市疟疾防治成果的巩固,将面临一个新的课题。

In ninth five-year-plan period, the malarious morbidity had been descended 84. 3%, from 31. 9/ 100000 in 1996 to 5.0/10000 in 2000, and the malaria disease control work focus has been turned to monitoring in Zhongshan city. We had examined 8256 cases of fever disease"three fever", the positive cases were 1277, positive rate was 15. 5%, and 277 patients were indigenous cases(21. 5%), 1011 patients were outlanders(78. 5% ). Base on the perfection of infrastructure, the relative stability of floating population, and the hard works of malaria disease control in ninth five-year-plan period, the main source of malaria had been turned from interior to importation, and the input case rate had ascended from 9. 1% to 46. 4%. This change will let us face to a new question about anti - malaria.
